In agricultural production, the work after the harvest of crops and fruits is to pull out the straws in the farmland to prepare for the planting of crops in the later stage. For example: cotton stalk or corn stalk, the traditional method is to manually pull out the stalk. The removed stalk is placed on the farmland and burned in the wild, causing serious air pollution. Therefore, the country is vigorously promoting the crushing of straw and returning it to the field. The purpose of reducing pollution and improving farmland soil. At present, there are very few agricultural machinery supporting this in China. Due to the large amount of straw, farmers need to manually pulverize the straw to return it to the field, and then sprinkle it back into the field. As a result, many local farmers are unwilling to return straw to the fields.

There are also some technical solutions for straw crushing and returning devices in the prior art. For example, a Chinese patent with an application number of 2015104886497 discloses a straw crushing and returning device, including a bottom plate, a support device, a scraper device, a conveyor belt device, Roller device and pulverizing device, the supporting device includes a first supporting column, a supporting table, a second supporting column, a third supporting column, a fixed plate, a first bracket and a first cross bar, and the pulverizing device includes a first frame body, a second frame body, the third frame, the first roller, the second roller, the first crushing teeth, the third roller and the second crushing teeth, the scraper device includes a second bracket, a first inclined rod, a scraper and a second inclined rod, The conveyor belt device includes a cushion block, a first support rod, a second support rod, a third support rod, a runner and a conveyor belt. The roller device includes a third bracket, a round wheel, a bump, a vertical rod and a horizontal rod. The third bracket is L One end of the third bracket is fixedly connected with the upper surface of the third frame body, and the other end of the third bracket is vertically downward.

This technical solution can fully pulverize agricultural materials such as straw, reduce the generation of garbage and incinerate the straw, but in this device, after the straw is put in, personnel are required to support the other end of the straw, which increases the personnel input on the one hand, and on the other hand.
